Turn Off Red LED on Raspberry Pi Ca,

The Pi camera module includes a red LED in one corner of the PCB. This lights up when the camera is active. It’s really useful in giving a visual indication that the camera is doing something and most of the time you will be glad it is there.

In my testing here are some of the reasons it can get in the way :
  • Pi Camera Module Red LEDIt can cause reflections on objects you are trying to photograph giving them a red glow.
  • For nature photography it scares animals.
  • For security applications it may draw unnecessary attention to the device.
  • It consumes power.

To disable the red LED you simply need to add the following line to your config.txt file :
disable_camera_led=1
To edit the config.txt file you can use Nano :
sudo nano /boot/config.txt
Use the arrow keys to scroll to the end of the file and add “disable_camera_led=1″ to the last line. Press “CTRL-x” to quit. If prompted press “Y” followed by “Return” or “Enter”.
Reboot your Pi with “sudo reboot” and when you next use the camera the red LED will be disabled.
